This new design is as simple and efficient as possible. It is built on the Costco Racking, with MacCourt Super tubs. The tubs are 36x24x8 made of molded polyethylene, by MacCourt here in the USA. They are available through Ace hardware and sometimes Lowes. They are much sturdier than the PVC utility tubs made in Israel, sold by Home depot. They are very sturdy and with just a few lath strips can overhang the rack a bit, allowing for three tubs per rack instead of just two per shelf.
The tubs are very simple to drill and drains are via one inch bulkheads. The Rack is topped with a 135 gallon acrylic aquarium and is plumbed to the central filtration system.
